Space frame

The Audi A8 replaced the V8 in 1994, with a aluminium space frame, known as the "Audi Space Frame" (ASF), to save weight. The weight reduction was offset by the quattro four-wheel drive system. It meant the car had similar performance to its rivals, but superior roadholding. The Audi A2 and Audi R8 also use Audi Space Frame designs.
